I liked too many things to count, but here's a few: 1. Crucible tournament IRON BANNER! Loved the idea of tournaments alone, but the fact weapons and gear actually were important made that a great day for any FPS player. 2. Free Roam 3. Tower graphics and interactions 4. Zooming around on a speeder bike to see a message saying "XXX_______XXX player is nearby". 5. Ogre boss and other ?? enemies areas. Means we will be revisiting areas and they. will. be. difficult. 6. Storyline interactions and moon mission end. That many enemies, the way those enemies were introduced (the hive swarming us too mind you), and other creative elements really make me happy that Bungie invested into those kinds of things. 7. Raids. Regardless of how others have complaints on them, hearing Lucas go on about how leadership ANd teamwork difficulty is what make shared world experiences unlike any other genre. Why? Beat it once? Great. Beat it on hard difficulty? Awesome. Beat it on the hardest possible difficulty with modifiers on all enemies? -blam!-in B-A-D-A-S-S.
